how specific is their history? can you, say, search 4pm last friday and see how much it was blowing while you were riding? If so, that is a cool feature. I have often spent days kiting where the wind obviously picked up while I was riding and was curious to know what the sensors say. (like last friday at 3rd)

I put together this website as another source for real time wind info:
http://www.windonthewater.comCell phone access, graphs, links to webcams, pressure gradients, etc.
Any feedback would be great.

I don't think so... it's a nice application, but if you were using it as your sole source right now and wanted to go kiting, you'd say "I guess it's not really blowing anywhere right now" because there's no sensor close to Sherman or Waddell -- the only two places in the area where it's blowing 20 right now.

Sorta gets back to the "how much is a good session worth to you" debate, IMHO. Free is nice, but you usually get what you pay for...
